Argue the toss in a twisted tale of logic...

In ir/rational you complete, create and discredit arguments by selecting propositions and filling in the blanks. It's a puzzle game based on propositional logic, and a graphic adventure all in one - only here you don't so much need to escape the room as prove why you'd even want to.

- Unique, language-based argument system: formulate logical proofs to progress through the game

- Dark philosophical comedy by Tom Jubert, writer of Penumbra, Driver: San Francisco and FTL.

- 10 screens and roughly half an hour of intelligent, challenging and inventive gameplay

- Musical score by award-winning composer Mikko Tarmia

My website:
My narrative design blog, Plot is Gameplay's Bitch:

- Click to progress story
- Complete the arguments by selecting options from the drop-down menus

NB Some systems don't display all the dropdown options at once, and you have to use the arrow keys to scroll.

If you can't see the right answer, chances are you can resolve the problem with the arrow keys. Hope it's not dampened your enthusiasm!

I thought it was an amazing game. The problems provided made me think without dulling my interest and the plot made me want more games like this. This has definitely been one of my favorite escape games.


Rated 5 / 5 stars

That was a truly amazing game. The challenge applied to one's logic skills was fantastic! I ask you to attempt to make a sequel or a similar game.

1. IF I enjoyed being challenged THEN I enjoyed the game
2. IF I enjoyed the game THEN I will wait for more like it
3. I enjoyed being challenged
4. THEREFORE I enjoyed the game
5. THEREFORE I will wait for more like it

Good luck in what ever you do man.

It's a very nice concept, gameplay wise at least. I haven't had any of the issues with interface or whatever that other people seem to be having. Perhaps It's just my choice of browser.
However, as shinobody mentioned, some of the logical assumptions made are slightly dodgy, and the plot was lacking a little. however, as is proved with the little code bit at the end, at least in the context of a game it doesn't really matter what the facts are, so long as for gameplay purposes you are aware that A is definitely A, and B is definitely B.

It would've been nicer if it had been a little longer, and if the puzzles had had a more practical application. If you're making a sequel, I think it'd be nice if some of the puzzles actively influenced what you did in-game. That way there are multiple endings, depending on how good your reasoning was throughout. While I appreciate that it was aiming for the whole 'mysterious sci-fi sadistic robot' theme, the fact that almost all the puzzles were just questions posed to you by an obscure little machine makes the plot feel slightly lacking.

However it's a very nice idea, and it'd be excellent if you could expand on it a little more.

The only thing I was thinking all game was "please no code or numbers, please no code or numbers, pleasFUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU UUUUUUUUUUUCK"

AWESOME GAME, make another one, this time with options, like multiple endings or something like that, for some people (not me) been killed in the end is a turn off
